There are times when you wonder about CPU or memory usage while using your computer.

If you use a third-party tool on a Mac, you can check the CPU, GPU, memory, SSD, network usage fan speed, temperature, etc. from the menu bar.

iStat Menu is the most famous, but also the most expensive. iStat Menu has been used for a long time, but there is a problem that you have to purchase a new one every time the major version changes.

I looked it up and found a free tool that is open source. as soon as Stats 이다.


The following items can be monitored.

  • CPU utilization
  • GPU utilization
  • Memory usage
  • Disk utilization
  • Sensors information (Temperature/Voltage/Power)
  • Battery level
  • Network usage
  • Fans speed
  • Fan control
  • Bluetooth devices



Built without the need to download and install code Download the latest version can do.


iStat Menu is prettier and has more detailed information, but it doesn't seem to make a huge difference in the menu bar. If you want to see the system status, this free program might be good for you.

Due to the heat of the palm, I checked the temperature on the menu bar and used the fan control function of Macs Fan Control or iStat Menu 6.   I bought the M1 MacBook.Since there is almost no heat, CPU usage or temperature is rarely checked in the menu bar. Sometimes I look at the menu bar to see how much SSD is left.
